Most "Dr Pepper cocktails" are really just bourbon poured over soda, and they taste like it: flat, one-note, and too sweet by the second sip. This one fixes that with two cheap ingredients. A half ounce of fresh lime juice and a couple of dashes of bitters cut straight through the sugar, so the drink reads as a proper highball with the soda doing the work of a mixer rather than carrying the whole glass. A little amaretto rounds it out and leans into the cherry-almond note people already taste in Dr Pepper, deepening the real thing instead of faking it.
The build is simple: 2 oz bourbon to 4 oz Dr Pepper, plus a half ounce each of fresh lime and amaretto and two dashes of bitters, all over ice. It is a smash in spirit more than technique, no muddling, just a tall, balanced long drink, and it comes together in about a minute with no shaker, no syrup, and nothing to cook down. Build it in the glass, pour the Dr Pepper last and slowly to keep the fizz, and finish with a lime wheel and a cherry. This is a drink for adults only: 21+, and please drink responsibly.
How to make a Dr Pepper bourbon cocktail
The whole thing is a build-in-the-glass highball, so there is no shaker and no special order to memorize beyond one rule: the Dr Pepper goes in last. Fill a tall glass with ice, add the 2 oz of bourbon, then the half ounce of fresh lime juice, the half ounce of amaretto, and two dashes of Angostura bitters, and give it a quick stir so the bitters and lime are evenly mixed before the soda goes in. Top with 4 oz of cold Dr Pepper, poured slowly down the side of the glass so it keeps its fizz, then one gentle stir and a lime wheel and cherry to finish. The full measurements and steps are in the recipe card below.
Why Dr Pepper works in this recipe
Bourbon and Dr Pepper share a backbone of vanilla, caramel, and warm baking spice, so the soda's 23 layered flavors sit right on top of the whiskey instead of fighting it. The trouble with soda highballs is always sweetness, and that is exactly what the lime and bitters are for: the acidity and the bitter edge pull the drink back into balance so the bourbon stays in front. The amaretto is the bridge, picking up Dr Pepper's cherry-and-almond character and giving the whole glass a little more body. Start from the original Dr Pepper for the classic profile, reach for Dr Pepper Cherry if you want the cherry note louder, or pour Dr Pepper Zero for a no-sugar version that drinks almost identically.
When to make it
At happy hour, this is the easy crowd-pleaser. There is no shaker and no special kit, so you can build a round in a couple of minutes and still hand everyone something that tastes like a real cocktail.
On game day, it scales effortlessly. Multiply the pour, keep the Dr Pepper cold, and let people top their own glasses so the fizz stays lively from first to last.
In summer, the lime and the long pour over ice make it genuinely refreshing, the kind of tall drink you actually want on a hot afternoon rather than a heavy spirit-forward sipper.
On date night, the garnish does the talking. A lime wheel and a cherry over ice look the part, and the drink is impressive out of proportion to how little effort it takes.
Tips and swaps
- Use fresh lime juice, not bottled; the bright acidity is the whole reason this tastes like a cocktail and not a spiked soda.
- Pour the Dr Pepper last and slowly down the side of the glass so you keep as much carbonation as possible.
- A higher-rye bourbon pushes the spice forward and plays beautifully with the soda's warm notes; a wheated bourbon keeps it softer and sweeter.
- No amaretto? A bar spoon of cherry liqueur or a splash of grenadine gets you close to the same cherry-almond lift.
- For a zero-sugar drink, build it with Dr Pepper Zero; the lime and bitters carry the balance either way.
- I tested this with both regular Dr Pepper and Dr Pepper Zero and it holds up either way; the one whiskey to avoid is a smoky, heavily peated one, which fights the soda's spice instead of complementing it.
If you like a spirit-forward Dr Pepper drink, this sits naturally alongside the Dr Pepper old fashioned and the Dr Pepper bourbon punch on the Dr Pepper recipes.
Frequently asked questions
Why add lime and bitters at all?
Because without them this is just bourbon and soda, which is sweet and flat. The half ounce of fresh lime adds acidity and the bitters add a dry, aromatic edge, and together they balance the sugar so the drink tastes like a real highball with the bourbon clearly in front.
What bourbon should I use?
A solid mid-shelf bourbon is ideal; you want enough character to stand up to the Dr Pepper without spending on a sipping pour. Rye whiskey also works and leans the drink spicier. Save your top bottle for drinking neat.
Can I make it without amaretto?
Yes. The amaretto deepens Dr Pepper's cherry-almond note, but the drink still works without it. A bar spoon of cherry liqueur or a small splash of grenadine gets you a similar lift, or you can leave it out entirely for a leaner, drier glass.
Can I batch it for a crowd?
Easily. Stir the bourbon, lime, amaretto, and bitters together ahead in a pitcher, then pour over ice and top each glass with Dr Pepper to order so every drink keeps its fizz. Topping with the soda last is the same trick that keeps the Dr Pepper bourbon punch lively, so no glass ever goes flat.
